7km in which direction? (I didn't know it was possible to be 7km from a subway station within SH city limits.) In any case, here's how I'd play it. When you visit the company, decide whether or not you'd be comfortable living in that area (ideally near the subway). If not, maybe Gubei would be a decent option (30 minute drive, but minimal traffic, good restaurants, and satisfies your outdoor requirement). Being close to their airport is also nice.
